PA 3100 HV Integrated Amplifier By T+A HiFi

PA 3100 HV Integrated Amplifier

The PA 3100 HV delivers world-class reference sound quality with a refined pre-amplifier section, redesigned analog mains, and a powerful voltage supply. Adding the optional PS 3000 HV power supply boosts performance and effortlessly drives even the most demanding speakers. With the option to include a High-End phono pre-amplifier or an analog signal processor module for tone and loudness control, this amplifier offers versatility and precision.

Superior Circuitry & Performance

Built with differential cascode amplification and discrete J-FET transistors, the PA 3100 HV offers unparalleled linearity and dynamic range. Its gas-tight gold-contact relays ensure durable, noise-free performance, while precision resistors and relays in the volume control guarantee flawless channel matching and distortion-free sound.
